I would like to instantiate an array of type T as such:
items = new T[maxQue];
Here is my code so far, I believe a non-reflective approach:
interface MyFactory<T>
{
T[] newObject();
}
public class Queue< T extends Comparable<T> > {
private int front;
private int rear;
private T[] items;
private int maxQue;
private static final int MAX_ITEMS = 1000;
public Queue(MyFactory<T> factory) {
maxQue = MAX_ITEMS + 1;
front = maxQue - 1;
rear = maxQue - 1;
items = factory.newObject();
items = new T[maxQue];
}
}
The { items = factory.newObject(); } works and resolves the compiler error but I do not know how to set the size of the array to maxQue using the MyFactory interface.
- How can I declare this array with a size of maxQue?
On a side note, while I know the definition of reflection in Java, can anyone please put it and the concept of factories in layman terms?
